Currently we have the ability to create questions for approval before allowing a new member into a group. However, when viewing the answers there is currently no way to save those answers to the contact record without retyping them. You can't even copy/paste because the answer field is greyed out. There also isn't a way to see the answers to the questions after you have approved the user.
I would love the ability to save the membership questions to the contact record so that I can review them later.
